CARBON-ASSORTING DEVICE.

Application filed June 19, 1912, Serial No. 704,699.

To all vwhom 'it may concern Be it knovvn that I, ADRIANUsM. DE JEU, a subject of the Queen of the Netherlands, residing at Cleveland, county of Cuyahoga, and State of Ohio, have invented certain new and useful Improvements in Carbon- Assorting Devices, of which the following is a specification.

My invention relates to assorting devices and particularly to devices especially adapted for assorting carbons such as are used in electric arc lamps.

lVhile I have hereinafter described my invention as a carbon assorting device it is to be understood that it is adapted for assorting any articles of similar form Within the capacity of the device.

The object of my invention is to provide an improved assorting device by means of which the straight carbons may be rapidly separated from the bent or crooked carbons.

A further object of my invention is to provide a device of the character under consideration which may be used for assorting carbons or other articles of different diameters without the necessity of adjusting the device for the various sizes.

'A further object of my invention is to provide improved means for feeding the carbons to the assorting device.'

ther objects Will appear hereinafter.

lVith these objects in view my invention `consists generally in an endless conveyer comprising a plurality of carriers suitably connected, a selecting device carried by each of the carriers for discarding crooked carbons, and means adapted to be set in operation by a crooked carbon for actuating the selecting device.

My invention further consists in a device as stated in Which the carriers are provided vvith rollers which are continually driven and upon which the carbons are adapted to rest.

My invention further lconsists in a selecting device characterized as above stated and in which, the selecting device is set in operation by the rotary motion of the carbon supported on the rollers, and further characterized by a yielding presser member to insure proper rotation ofthe carbon.

My invention further consists in a selecting device comprising a plurality of con- Specication of Letters Patent.

nected carriers and means for depositing the carbon from a magazine or hopper one at a time upon said carriers.

My invention further consists in various details of-construction and arrangements of parts all as Will be fully described hereinafter and particularly pointed out in the claims.

My invention Will be more readily understood by reference to the accompanying drawings forming a part of this specification and in Which- Figure l is a diagrammatic side elevation of a selecting or assorting device and feed mechanism for the same, embodying my invention in its preferred form. Fig. 2 is a side elevation of the assorting'device upon an enlarged scale and illustrating the adjacent end of the feed mechanism. Fig. 3- is a detail transverse section of the selecting device illustrating one of the carriers in front elevation and the parts in the position they assume when a straight carbon is deposited upon the same. Fig. 4 is a plan view of one of the carriers and the adjacent portions of the track upon which it is mounted. Fig. 5 is a vievv similar to Fig. 3 illustrating the parts in the position they assume after having been actuated by a bent carbon, a bent carbon being shown in the carrier'and passing under the presser member. Fig.- 6 is adetail longitudinal section illustrating a plurality of carriers, each With its carbon, passing under the presser member. Fig. 7 is a detail longitudinal section at the discharge end of the device illustrating the final steps in separating thel straight from the crooked carbons. view of the frame of the selecting device, the carriers being removed. Fig. 9 is a perspective view of one end of one of the carriers, and Fig. l0 is a detail transverse section of one of the carriers taken on the line mof Fig. 4 and illustrating a slight modication.

Referring'novv to the drawings A indicates the frame of the assorting mechanism,

'B the conveyer thereon comprising a plurality of connected carriers C, D th'e presser member, E the feed mechanism forde'positing the carbons one at a time on the carriers C and F the table or magazine from which the carbons are fed.

The frame A comprises a pair of upper Fig. 8 is a top plan' longitudinal members 1 1, a pair of lower longitudinal members 2, vertical members 3 3 rigidly connecting the upper and lower members 1 and 2 and extended downwardly forming legs 4 4 for the device, and transverse brace members 5 rigidly connecting the members 3. The upper members 1 1 are parallel and substantially horizontal, and form tracks for the upper lap of the conveyer B to travel upon. The lower members 2 2 are similarly arranged and serve as tracks for the lower or return lap of the conveyer. The ends of the lower members 2 are extended beyond the ends of the members 1 to support upwardly extending brackets 6 6 provided with bearings 7 for shafts 8 of wheels 9 9 upon which the conveyer is mounted. The upper edges of the members 1 are in a plane vsubstantially tangent to the top of the wheels 9 and the ends of said members are shaped as at 10 to conform to the peripheries of said wheels in order to bring the upper edges or tracks 11 as close to the wheels 9 as possible, so that the carriers shall pass from the tracks and on to the wheels without dropping or sagging the conveyer.

Secured to the inner faces of the members 1 and extending longitudinally thereof a considerable distance from the feed end of the device is a pair of contact plates 12 and 13, connected respectivelyT by conductors 14 and 15 to the opposite poles of abattery 16 or other source of electric supply. Also secured to the inner faces of the members l are ianges 17 which constitute cam tracks and which extend upwardly and forwardly from points beneath the contact plates 12 and 13, that is, the adjacent ends of the cam tracks 17 and the contact plates overlap for a urpose which will appear hereinafter. upported above the discharge end of the device is a pair of bars 18. These bars extend from points above the adjacent end of the cam tracks 17 horizontally to points aboveI ,the adjacent wheels 9, and are then curved forwardly and downwardly as at 19, and serve as lguides or ways for the crooked and discarde' carbons. l

The endless conveyer B is composed of a plurality of sil'nilar carriers C and as these carriers are all identical in construction and operation a detailed description of one will be suflicient. In Figs. 3, 4, 5 and 9 I-have illustrated a carrier in detail. Each ca"rrier comprises an elongated body member 20 bon X as indicated in Figs. 3, 5 and 6. As

the carbons rest upon the peripheries of the rollers 22 it is obvious that a rotary motion is imparted to them. If preferred the brackets 21 may be recessed as at 23 in their upper edges between the rollers to avoid contact with the carbon. This will depend upon the distance between the rollers 22 of each pair and the diameter of the carbon or other device carried thereby.

Each carrier is equipped with a selecting device which is electrically set by means of the rotating crooked carbon and mechanically operated. Mounted for vertical reciprocation adjacent each end of the carrier is a vertically disposed rod 24. These extend through suitable apertures formed in the body 20 and are provided at their upper 'ends with forked or recessed members 25 which normally lie beneath the carbon and spaced therefrom so as not to interfere with the Arotation of the same.

26 indicates a collar on the rod 24 to limit the downward movement. A pair of brackets 27 27 extend downwardly from the body, 20 toward the center, and in the lower ends of these brackets are pivotally supported substantially horizontally disposed levers 28 which are adapted to actuate the rods 24 to lift a crooked carbon from .the rollers 22. The lower ends of the rods 'mounting the same on the brackets '27 and to extend through the slots 29. The inner ends 31 and the outer ends 32 are 'bent into horizontal position as indicated, the inner ends to be engagedby a centrally arranged vertically reciprocating plunger 33 and the outer ends to engage the cam tracks 17 in the manner hereinafter described. The plunger 33 is arranged at the center of the carrier and mounted for vertical reciprocation therein. Its lower end is provided with an enlarged head 34 to engage the ends 31 of the levers and between said head andthe body 20 is interposed a springi 35. The plunger 33 is normally retracte o1 heldin raised position permitting the levers to drop into the positions shown in Fig. 3. in which positions the en'ds 32 are below the lowermost ends of the cam tracks 17.

When the plunger is released by a crooked carbon, in a manner hereinafter described, it depresses the inner ends of the levers 28 and raises the outer ends above the level of the lower ends of the cam tracks and as the carrier moves forwardly said cam tracks elevate the levers Yand. the rods 24, raising the carbons from the vrollers 22 and into position to be engaged by, or deposited upon the bars 18. Extending through the upper end of the plunger 33 is a horizontally disposed pin 36, one end of which is arranged in a vertically disposed guide 37 secured to the upper face of the carrier.

llt is obvious that if a crooked carbon is supported in the carriers it will be necessary to initially actuate the levers 28 by releasing the plunger 33 before the carrier reaches the rear or lowermost end ofthe camtracks 17. To this end l provide the following electrically operated controlling mechanism. Fixed to the respective ends of the carrier body 20 are spring tongues 38 and 39 which serve as wipers to engage the electrically connected contactplates 12 and 13 hereinbefore described. 40 indicates an upwardly and inwardly extending spring tongue secured to the upper face of the carrier body and terminating in an upturned end 41 adjacent the center of the carrier. The tongue 40 is electrically connected to the wiper 39 and is preferably formed integrally therewith as illustrated clearly in Fig. 9. An adjustable arm 42 limits the upward movement of the tongue 40 and is electrically connected to the wiper 38. 43 indicates an electromagnet arranged in the circuit between the arm 42 and the wiper 38. Pivotally mounted on the carrier body 20 as at 44 is' a lever one arm 45 of which is arranged above the electromagnet 43 and the other end 46 extending beneath the pin 36. As hereinbefore stated the contact plates 12 and 13 extend yto the feed end of the members 1 and it is obvious that as soon as the wipers 38 and 39 engage said plates, and as long as the tongue 40 engages the arm 42, the electromagnet 43 will be energized, attracting the arm 45 and raising the arm,46, thereby raising the plunger .33 and maintaining the same in retracted position. This allows the ends 32 of the levers 28 to drop, andy unless the circuit above described is broken, said ends 32 will remain depressed and pass under the cam track 17. The end 41 of the tongue 40 extends upwardly almost to engagement with a straight carbon resting upon the rollers 22, and it is therefore obvious that if the bent 'carbon is supported upon the rollers and rotated thereby it will engage the end/ 41, depress the tongue 40 and break the circuit. This denergizes the electromagnet 43, releases the plunger 33 and permits the same to actuate the levers -28 to raise the ends 32 above the plane of the ends of the cam tracks 17 Agfter the circuit through .the electromagnet 43 has-been broken by means'of a' crooklits sensitiveness with relation to the egr for maintaining the broken circuit.

48 indicates a spring tongue fixed to the body 20 and lying substantially parallel with the tongue 40. This is electrically connected, as indicated at 49, with one end of the winding of the electromagnet 47 and its free end is off-set as at 50 to extend beneath the tongue 40. The end 50 is upturned as illustrated and lies in close roximity to said tongue. The other end ofp the winding of the electromagnet 47 is electrically connected as indicated at 51 to the wiper 38. It is obvious that when the tongue 40 is depressed out of engagement with the arm 42 and thereby breaking the circuit to the electromagnet 43, the circuit will be made through the electromagnet 47.

52 indicates a lever pivotally mounted on the carrier, one end 53 of which constitutes an armature for the electromagnet 47 and is attracted and depressed by said electromagnet when energized. The arm 53 is provided with an oif-set tongue 54 which engages the tongue. 40 when depressed and holds the same out of engagement with the arm 42, in this manner maintaining a broken circuit to the electromagnet 43. The opposite end of the lever 52 is weighted as at 55 to restore the lever to normal position when the electromagnet 47 is denergized.

In order that the'device may be used t0 assort carbons or other articles o'f either large or small diameter, and also in order that the device may be adjusted to regulate ee of curvature of the artioles,vI adjustably mount the arm 42. By raising or lowering said arm the height of the end 41 is regulated. If articles of large diameter are to be assorted it is obvious that when resting upon the rollers 22 their lower ed es will be at a greater distance from the bo y 20 than when articles of smaller diameter are resting thereon. Consequently it is necessary to raise the end 41, which may be done by raising the arm 42. Conversely when articles of smaller diameter are being assorted it is necessary to lower the Ipnd 41v as they lie closer to the body 20. llt is also obvious that this adjustment Will regulate the sensitiveness of the device to different degrees of curvature of the articles being assorted. To

Asecure the proper adjustment and maintain the proper electrical connection, a bar or conductor 56 is secured to the front face ofV engaging the bar 56 and through which a set screw 58 extends. If a wide range of adjustment is desired I provide an insulated lug or tongue 59 lon the arm 42 which engages the tongue 48 and maintains proper relative position between the tongue 40 and the contact ends 50 of the tongue 48. This modified form is illustrated in Fig. 10.

To insure proper rotation of the carbons on the carriers, I provide the presser members D. This comprises a yoke or bracket 60 spanning the frame A adjacent the feed end, vertically disposed rods 61 extending through perforations therein, horizontal longitudinally disposed shoes 62 at the lower ends of said rods and springs 63 interposed between said bracket and said shoes whereby said shoes are held in yielding engagement with -the carbons X.

I do not limit my invention to the particular arrangement of the shoes 62, but I prefer to provide two such shoes as illustrated and arrangethem toward the sides of the device in order to. engage the carbons adjacent their ends, by which arrangement one or more straight carbons under the shoes will not prevent engagement with and proper rotation of the bent carbons. In Fig. 6 I have illustrated three carriers and the carbon supported thereby passing under the presser members, the carriers traveling in the directionof the arrow. The carbons in -the right hand and center carriers are indicated as being straight and the one in the left hand carrier as being crooked, and it will be noted that in the former the levers 28 have not been actuated whereas in the latter it has, as has also the spring tongue 40. 'The several carriers C are connected at the ends by links c which are preferably secured to the shafts of the rollers 22, thereby uniting the carriers into an endless conveyer.

The feed mechanism comprises an endless belt provided with spaced slats, a magazine table and suitable mechanism for feeding the carbons one at a time from the table to the slats onjsa-id belt. 64 indicates the belt, 65 the slats, F the table and 66 the mechanism for feeding the carbons from the table to the belt. The table F is inclined and its lower end is arranged above the belt 64. At the discharge end of the magazine table is 'arranged a reciprocating member 67 which is actuated intermittently'by a cam wheel 68 on the shaft of one of the belt drums 69 to feed ythe carbons one at a time to the slats: 65 on the belt. The discharge end of the belt 64 is arranged adjacent the feed end of the -assorting device proper and said belt deposits the carbons upon forwardly projecting arms 70. Each of the carriers is provided with a pair of upwardly and slightly rearwardly inclined arms 71 which lift the carbons from the arms and deposit the same upon the rollers 22.

One of the shafts 8 is extended and provided with a pair'of pulleys 72 and 73 respectively. A belt 74 extends from a motor not shown, to the pulley 72, and a belt 75 extends from the pulley 73 to the pulley 76 0n one of the shafts of the belt 64, by which arrangement the conveyer B'and belt 64 are simultaneously driven and properly timed. In this connection it should be noted that the peripheries of the wheels 9 are recessed as at 77 to receive portions of the rollers 22.

The operation of the device is as follows: The carbons, or other articles to be assorted, are placed upon the inclined table F and the device set in motion. The cam wheel 68 causes reciprocation of the member 67 allowing one carbon at a time to drop upon the belt 64, and the cam wheel is 4so time that one carbon is dropped between the successive slats thereon. The belt or apron 64 deposits the carbons one at a time upon the arms 70, and the conveyer B is so timed that the arms 71 thereon remove each earbon from the arms 70 before another carbon is deposited thereon. This transfer of the carbons to the conveyer takes place as the carriers are passing upwardly around the wheels 9 at the feed end of the device and just above the center thereof, and as the carriers pass upwardly to the top of said wheels the carbons are rolled inwardly on the arm 71 and deposited with their ends resting upon the wheels 22. As the carriers reach the top of the wheels, or on a level with the track 11, the wipers 38 and 39 come in contact with the contact plates 12 and 13 respectively, closing the circuit through the electromagnet 43 and energizing the same. The energized electroniagnet 43 actuates the lever 45---46 and raises the plunger 33, permitting the ends 32 of the levers 28 to drop below the level of the lower rear end of the cam tracks 17. Further movement brings the carbons `beneath the presser member or shoes 62' thereby insuring rotation of the carbons. If the carbon is straight it passes on through the device -and is dropped from the conveyer B at the discharge end thereof into a suitable receptable provided for their reception but not `illustrated in thedrawing. When a crooked or bent carbon is rotated upon the rollers 22 and beneath the presser shoe 62 it engages and depresses the end 41 of the spring tongue 40, breaking the circuit to the. electromagnet 43 as hereinbefore described and closing the circuit t'o the electromagnet 47. This releases the plunger 33 which in turn raises the ends 32 of the levers 28 above the level of the rear end of the cam tracks 17 and the arm 54 insures the parts remaining in this position until the ends 32 of the levers are Well upon the tracks 17. It is for this purpose that thl adjacent ends of the contact plates 12 and 13 and of the tracks 17 overlap, which arrangementalso insures the passage of the ends 32 beneath the track 17 when a straight carbon is on the carrier. Further movement of the carrier with the crooked carbon causes the ends 32 to ride up on the cam tracks 17, thereby raising the rods 24: and lifting the carbon from the rollers 22 above the level of the bars 18 upon which they deposit the same. This action is clearly illustrated in Fig. 7 of the drawings, the carriers moving in the direction oi' the arrow. After the bent carbon is deposited upon the bars 18 the arms 71 move the same along thereon to the bent end whence they rolll off into a separate receptacle not shown.
